Abstract

Manganese(i) tricarbonyl complexes such as [Mn(bpy)(CO) ₃ L] (L = Br, or CN) are known to be electrocatalysts for CO ₂ reduction to CO. However, due to their rapid photodegradation under UV and visible light, these monomeric manganese complexes have not been considered as photocatalysts for CO ₂ reduction without the use of a photosensitizer. In this paper, we report a cyanide-bridged di-manganese complex, {[Mn(bpy)(CO) ₃ ] ₂ (μ-CN)}ClO ₄ , which is both electrocatalytic and photochemically active for CO ₂ reduction to CO. Compared to the [Mn(bpy)(CO) ₃ CN] electrocatalyst, our CN-bridged binuclear complex is a more efficient electrocatalyst for CO ₂ reduction using H ₂ O as a proton source. In addition, we report a photochemical CO ₂ reduction to CO using the dimanganese complex under 395 nm irradiation.
